Specification of Letters Patent.

" Application led April 19, 1912. Serial No. 691,947.

To all whom it may concern? Be it known that I, EUGENE E. SCHMITT,

a citizen of the United States, residing at.

St. Louis city, State of Missouri, have invented new and useful Improvements in Door or Window Closures, of which the following is a specification.

This invention relates to door or window closures and the principal object'of the invention is to provide a simple and eilicient closure which will prevent fire drafts and will cut off all communication between different parts of the building against such drafts. y

rlhe particular use of the invention is for closin elevator hatches or stair shafts so re can notpass through the usual openings between the wall and the frame of the doors 0r between the /sill and the bottom of the doors between the top and the hangers.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which:-

Figure 1 is an elevation showing the device applied to close the elevator shaft and with parts broken away. Fig. 2 is a horinzontal section on the line 2-2 of Fig. 1. Fig. 3 is a vertical section on the line 3`3 of Fig. 1. Fig. 4 is an enlarged detail vertical section showing the connection between the doors of the upper portion thereof. Fig. 5 is a perspective view of the soiit member. Fig. 6 is an enlarged horizontally sectional view.

Referring more particularly to ,the drawings, l represents a suitable frame or the wall aroundthe opening 2. Secured to this frame or to the wall and extended across the opening is a cornice vpiece 3, towhich 1s secured av grooved member 4, whose flanges 5 are increased inwidth, as shown at 6, for a purpose to be hereinafter described. rlhis member extends partially across the door and has abut-ting its narrow end a stationary door' section 7 which is secured to the frame or wall by an angle bar 8 which vthe shaft is fully filled, with fiame. the arrangement prevents drafts and theV extends the full length of the door. The vertical edge of this door which is farthest within the opening has secured thereto an angle bar 9, which in conjunction with the door 7 forms a channel 10 adapted to receive the short legof a similar angle bar' 11 secured to the right hand vertical edge this door carries an angle bar 13 which forms with the door section a channel 14 adapted to receive the short angular end of the angle bar 15 carried upon the door section 16. These angle bars efectually interlock so as to prevent the draft from passing between the doors and the door 16 is provided with an angle bar 17 which with the door, forms a channel 18 adapted to be entered by an angle bar 19 carriedby the frame or wall. The upper portion of the door section 12 has secured thereto a tongue and grooved member 20, whose tongue 21 is adapted to travel between the flanges 6 of the member 5 Aand whose groove` 22 is adapted to receive the tongue 23 upona tongue member 24 carried upon the top of the door section 16. The tongue 23 is also adapted to travel between the wide portion of the flanges 6 when the door 16 isin fully closed position. Each of these door sections 12 and 16 have secured thereto suitable hangers 25 which travel upon tracks 26 extending across the frame and each of the door sections 7, 12 and 16 are provided with transverse ribs 27 projecting from their lower edges and adapted -to enter grooves 28 formed in the sill piece 29. It will be readily seen that when thesev door sections areclosed across the opening that the angle Vbars will readily interlock or interengage each other so as to prevent the escape of flame into a room or hall even if Also tongue .and groove connection between the doors and the frame makes the movement of the doors more certain.

What claim is:-

In combination, a door or window frame,-
